I might have a spare 4MB VSIMM somewhere, I added SX support for both
kernel and X a while ago.
That being said, the main reason we don't have rasterflex support is
lack of hardware in my hands. I've been regularly checking ebay for any
non-Sun SBus graphics hardware, with very little success. If I found
anything it was rebadged cg3 and cg6.
Someone(tm) send me an mgx ( basically a 4MB PCI VGA behind a custom
SBus-PCI bridge thing ), which has driver support now. Got to finish hw
acceleration in X, 24bit works.
Also, I've seen a few S24 floating around on ebay, usually mislabeled
Basically a tcx with 4MB VRAM and a newer DAC that supports 24bit,
WIDs, and a hw cursor. Should Just Work(tm).
Says he ships only to the US but who knows, one can always ask.
